Acoustic mapping on three-dimensional models
Proceedings of the 12th International Conference on Computer Systems and Technologies - CompSysTech '11, 2011This paper describes a method to visualize sound using beamforming (Acoustic Camera). After a short introduction the simplest beamforming method (delay and sum) will be illustrated. Furthermore, the transition from the two-dimensional to the three-dimensional acoustic mapping will be described.

Multipulse acoustic mapping system
Marine Geodesy, 1989Abstract A concept of a novel seafloor surveying and mapping system is described. The system consists of a pencillike, narrow‐beam transmitter and a fanlike, broadbeam receiver. The transmitter beam is sequentially scanning a certain angular sector situated within the receiver beam coverage.

GPU-based acoustical occlusion modeling with acoustical texture maps
Proceedings of the 6th Audio Mostly Conference: A Conference on Interaction with Sound, 2011Although the direct path between a sound source and a receiver is often occluded, sound may still reach the receiver as it diffracts ("bends") around the occluding obstacle/object. Diffraction is an elementary means of sound propagation yet, despite its importance, it is often ignored in virtual reality and gaming applications altogether except perhaps

Undersea acoustic communication maps for collaborative navigation
2012 IEEE/OES Autonomous Underwater Vehicles (AUV), 2012Communications play a key role in collaborative navigation algorithms. A better understanding of the ability to send and receive messages permits greater navigational flexibility and system robustness. This paper focuses on the building of an underwater acoustic communications map for collaborative navigation. The emphasis is in two areas - a local and

Acoustic Mapping and Localization of an ROV
2006 14th Mediterranean Conference on Control and Automation, 2006This paper summarizes the work done on the development of a module to interface a commercial mechanical scan sonar within an ROV control architecture and its integration with the other modules. The sonar module fulfills the scope of endowing the ROV with an open tool for the management of the sonar setting, adapting sonar performances to the specific ...

Mapping Environmental Sounds Using Google Map (Acoustic Maps)
2018 International Conference on Advanced Science and Engineering (ICOASE), 2018Modern lives are dominated by what people see, and so there are many travel guides described wonderful places to visit. However, the sounds of these places are part of the experience. In some cases, what people hear is more important and interesting than what they see.

Acoustic-to-articulatory mapping of fricatives
The Journal of the Acoustical Society of America, 1995This research considers the acoustic-to-articulatory mapping of fricative speech. By incorporating additional knowledge about fricative production, perception, and dynamics into the mapping scheme, improved performance may be achieved over standard acoustic-to-articulatory mapping techniques.

Acoustic archeological mapping method
The Journal of the Acoustical Society of America, 1981A method of locating near-surface underground chambers, rooms, caves, pits, tubes, faults in surface rocks, and the like, using acoustic techniques is disclosed. For mapping large areas, a survey grid for transmitter transducer placement first is laid out over the area of interest.

Visualizing acoustic similarities between emotions in speech: an acoustic map of emotions
Interspeech 2007, 2007In this paper, we introduce a visual analysis method to assess the discriminability and confusiability between emotions according to automatic emotion classifiers. The degree of acoustic similarities between emotions can be defined in terms of distances that are based on pair-wise emotion discrimination experiments.

Acoustic Mapping within the Heart
The Journal of the Acoustical Society of America, 1956A cylindrical barium titanate element has been placed at the distal end of a specially designed catheter and used in studies of heart sounds of dogs and humans. The heart sounds have been recorded with the sensitive catheter located directly in the heart and in the pulmonary artery.
